WIRING
All wires must be sized per NEC (National Electrical Code) or CEC
(Canadian Electrical Code) and local codes. Use Electrical Data table
MCA (minimum circuit amps) and MOCP (maximum over current
protection) to correctly size the wires and the disconnect fuse or
breakers respectively.
Recommended Connection Method for Power and Communication
Wiring:
The main power is supplied to the outdoor unit. The field supplied 14/3
stranded wire with ground with a 600 volt insulation rating,
power/communication wiring from the outdoor unit to indoor unit
consists of four (4) wires and provides the power for the indoor unit.
Two wires are line voltage AC power, one is communication wiring (S)
and the other is a ground wire. Wiring between indoor and outdoor unit
is polarity sensitive. The use of BX wire is NOT recommended.
If installed in a high Electromagnetic field (EMF) area and
communication issues exists, a 14/2 stranded shielded wire can be used
to replace L2/N and (S) between outdoor unit and indoor unit landing
the shield onto ground in the outdoor unit only.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Wires should be sized based on NEC and local codes.
CAUTION

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Be sure to comply with local codes while running wire from
the indoor unit to the outdoor unit.
Every wire must be connected firmly. Loose wiring may cause
the terminal to overheat or result in unit malfunction. A fire
hazard may also exist. Ensure all wiring is tightly connected.
No wire should touch the refrigerant tubing, compressor or
any moving parts.
Disconnecting means must be provided and shall be located
within sight and readily accessible from the air conditioner.
